Image Encoding Apparatus and Method for Controlling the Same and Non-Transitory Computer-Readable Storage Medium

2. The apparatus according to claim 1, wherein the determination unit is operable to perform weighting using weighting coefficients, which correspond to the information representing compression ratios acquired by the acquisition unit, to determine the quantization parameters.

3. The apparatus according to claim 2, wherein the determination unit is operable to determine a sub-band to be weighted among the plurality of sub-bands based on the information representing the compression ratios acquired by the acquisition unit.

4. The apparatus according to claim 1, wherein the determination unit is operable to switch between weighting an LH sub-band or an HL sub-band in accordance with the compression ratios acquired by the acquisition unit.

11. The apparatus according to claim 10, wherein in a case where the information representing the compression ratios selected by the user indicates compression ratios in which more compression has been performed in the horizontal direction than in the vertical direction, the determination unit is operable to determine a quantization parameter to be applied to an HL sub-band to be smaller than a quantization parameter to be applied to an LH sub-band of the same decomposition level.

12. The apparatus according to claim 1, further comprising a plane conversion unit configured to convert an image obtained by the image capturing unit into a plurality of planes, each configured by a single component, wherein the transform unit is operable to wavelet transform each plane obtained by the plane conversion unit.
